Product Overview
The Woodward 9907-164 is a microprocessor-based governor control unit from the 505/505E series, engineered for precise regulation of steam turbines, turbogenerators, and turboexpanders. As a core component of Woodward’s industrial control portfolio, the 9907-164 integrates digital processing with robust field-configurable hardware to manage critical parameters such as speed, load, and pressure. It operates by controlling a turbine’s single extraction or admission valves using split-stage actuators, ensuring optimal steam flow dynamics. The unit features a user-friendly interface with a 2-line, 24-character display and 30-key keyboard, enabling on-site configuration via menu-driven software. With support for modular I/O expansion and communication protocols like Modbus, the Woodward 9907-164 serves as a flexible solution for enhancing operational efficiency and safety in energy and process industries .

Main Features and Advantages
The Woodward 9907-164 excels in high-precision control through digital algorithms, enabling accurate speed and load management for turbines. Its critical speed avoidance function prevents operation at resonant frequencies, while valve limiters and auto-start sequences optimize turbine performance. The unit supports real-time data acquisition for parameters like pressure and temperature, coupled with self-diagnostic capabilities for fault detection. Integration with HMI/SCADA systems is seamless via Modbus, and the front-panel interface allows field reconfiguration without additional tools. These features ensure reliability in harsh conditions, reducing downtime and maintenance costs .
Application Areas
The Woodward 9907-164 is deployed in sectors requiring precise turbine control, such as power generation (e.g., cogeneration plants, biomass facilities), oil and gas (pipeline compressors, refinery turbines), and industrial manufacturing (paper mills, chemical processing). It also supports turboexpanders in cryogenic applications and mechanical drive systems for pumps/fans. By ensuring stable operation under variable loads, the controller enhances safety and efficiency across these critical infrastructures .
